According to the American Cancer Society, more than 11.4 million Americans are currently living with cancer. While cancer treatments are plentiful, many have negative side effects. Previous studies have indicated that a significant number of patients who receive chemotherapy also experience cognitive declines, including decreases in verbal fluency and memory. Now, one University of Missouri health psychologist has found evidence that indicates Tai Chi, a Chinese martial art, might help overcome some of those problems.

"Scientists have known for years that Tai Chi positively impacts physical and emotional health, but this small study also uncovered evidence that it might help cognitive functioning as well," said Stephanie Reid-Arndt, assistant professor and chair of the Department of Health Psychology in the School of Health Professions. "We know this activity can help people with their quality of life in general, and with this new study, we are encouraged about how Tai Chi could also help those who have received chemotherapy. I also hope this encourages more people to think about Tai Chi positively on a broader scale in their lives."

Tai Chi involves practicing slow motion routines and is based on several principles, including mindfulness, breathing awareness, active relaxation and slow movements. The emphasis on slow movement makes Tai Chi particularly suited to a wide range of fitness levels, which makes it very relevant for those who have had chemotherapy and might be experiencing physical limitations as a result, Reid-Arndt said.

The MU pilot study followed a group of women with a history of chemotherapy. The women participated in a 60-minute Tai Chi class two times a week for 10 weeks. The women were tested on memory, language, attention, stress, mood and fatigue before and after the 10-week sessions. According to Reid-Arndt, the results of the tests indicated that the women had made significant improvements in their psychological health and cognitive abilities.

"Tai Chi really helps individuals focus their attention, and this study also demonstrates how good Tai Chi could be for anyone, whether or not they have undergone treatment for cancer," Reid-Arndt said. "Due to the small size of this study, we really need to test a larger group of individuals to gain a better understanding of the specific benefits of this activity for patients who have been treated with chemotherapy and how significant these improvements might be."

###The study was published recently in Complementary Therapies in Clinical Practice.

An Indiana University study that exposed older veterans with stroke to yoga produced promising results as researchers explore whether this popular mind-body practice can help stroke victims cope with their increased risk for painful and even deadly falls.

The pilot study involved 19 men and one woman, average age of 66. For eight weeks, they participated in a twice weekly hour-long group yoga class taught by a yoga therapist who dramatically modified the poses to meet the veterans' needs.

A range of balance items measured by the Berg Balance Scale and Fullerton Advance Balance Scale improved by 17 percent and 34 percent respectively by the end of the program. But equally exciting to lead researcher Arlene A. Schmid, rehabilitation research scientist at the Richard L. Roudebush VA Medical Center in Indianapolis, was the measurable gain in confidence the study participants had in their balance.

"It also was interesting to see how much the men liked it," said Schmid, assistant professor of occupational therapy in the School of Health and Rehabilitation Sciences at Indiana University-Purdue University Indianapolis. Many of the veterans wanted the study to continue or asked for a take-home exercise plan so they could continue the practice. "They enjoyed it so much partly because they weren't getting any other treatment. They had already completed their rehabilitation but felt there still was room for improvement."

Schmid discussed her findings at the American College of Sports Medicine meeting in Denver during her poster presentation, "Preliminary Evidence of Yoga on Balance and Endurance Outcomes for Veterans with Stroke" in the session for Fitness and Performance Testing for Posture, Stability and Balance.

Statistics concerning strokes and falls are grim, with studies showing that strokes can quadruple the risk of falling and greatly increase the risk of breaking a hip after a fall. An estimated 80 percent of people who have strokes will also have some degree of impaired balance.

The study participants performed poses initially while seated in chairs and then progressed to seated and standing poses. Eventually, they all performed poses on the floor, something Schmid considers significant because of a reluctance many older adults have to working on the floor.

"Everything was modified because we wanted them to be successful on day one," Schmid said. "Everyone could be successful at some level."

A score of less than 46 on the Berg Balance Scale indicates a fall risk. Schmid said the study participants on average began the study with a score of 40 and then improved to 47, moving them past the fall risk threshold. The study participants also showed significant improvements in endurance based on a seated two-minute step test and a six-minute walk test.

Schmid said research into therapeutic uses for yoga is "really taking off," particularly in mental health fields. Clinically, she has been watching a small trend of occupational therapists and physical therapists also becoming yoga therapists. The yoga performed in the study was modified to the extent that Schmid said it would be very difficult to find a comparable class offered publicly. Such a class should be taught by a yoga therapist who has had additional training in anatomy and physiology and how to work with people with disabilities. Schmid hopes to expand the study so she and her colleagues can explore whether such classes are effective on a larger scale.

Veterans of the Iraq/Afghanistan wars showed a 50 percent reduction in their symptoms of post-traumatic stress disorder (PTSD) after just eight weeks of practicing the stress-reducing Transcendental Meditation technique, according to a pilot study published in the June 2011 issue of Military Medicine (Volume 176, Number 6).

The study evaluated five veterans, ages 25- to 40-years-old, who had served in Iraq, Afghanistan or both from 10 months to two years involving moderate or heavy moderate combat.

The study found that Transcendental Meditation produced significant reductions in stress and depression, and marked improvements in relationships and overall quality of life. Furthermore, the authors reported that the technique was easy to perform and was well accepted by the veterans.

The Clinician Administered PTSD Scale (CAPS) was the primary measure for assessing the effectiveness of TM practice on PTSD symptoms. CAPS is considered by the Department of Veterans Affairs as the "gold standard" for PTSD assessment and diagnosis for both military Veteran and civilian trauma survivors.

The paper's senior researcher, Norman Rosenthal, M.D., is clinical professor of psychiatry at George

"Even though the number of veterans in this study was small, the results were very impressive," Rosenthal said. "These young men were in extreme distress as a direct result of trauma suffered during combat, and the simple and effortless Transcendental Meditation technique literally transformed their lives."

The findings were similar to those from a randomized controlled study of Vietnam veterans conducted by researchers at the University of Colorado School of Medicine. In that study, published in the Journal of Counseling and Development in 1985, after three months of twice-daily TM practice, the veterans had fewer symptoms than those receiving conventional psychotherapy of the day. In fact, most of the TM-treated subjects required no further treatment.

"Even though the combat experiences of OEF/OIF veterans and Vietnam veterans are quite different, the fact that our study corroborates the results of the previous study tells us that this technique has the potential to be an effective tool against PTSD and combat stress, regardless of combat situation," explained Sarina Grosswald, EdD, co-researcher on the study.

Rosenthal hypothesizes that Transcendental Meditation helps people with PTSD because regular practice produces long-term changes in sympathetic nervous system activity, as evidenced by decreased blood pressure, and lower reactivity to stress. "Transcendental Meditation quiets down the nervous system, and slows down the 'fight-or-flight' response," he said. People with PTSD show overactive fight-or-flight responses, making them excellent candidates for Transcendental Meditation.

Rosenthal points out that there is an urgent need to find effective and cost-effective treatments for veterans with combat-related PTSD. "The condition is common, affecting an estimated one in seven deployed soldiers and Marines, most of whom do not get adequate treatment. So far, only one treatment—simulation exposure to battleground scenes—has been deemed effective, but it requires specialized software and hardware, trained personnel and is labor intensive.

A new report paints a stark picture of the toll on the U.S. military of almost a decade of war: higher stress and lower morale. The report, released Thursday, May 19, 2011, at the Pentagon, relied on questions to soldiers and Marines in Afghanistan in July and August of last year and compared responses with similar surveys in 2005 and 2009. The report noted "significant decline in reports of individual morale" as well as "acute stress rates significantly higher" than in earlier years.

"Research suggests that 18% to 30% of Vietnam veterans, 10% to 20% of Iraq War veterans, and 5% to 15% of Gulf War veterans have experienced PTSD," says U.S. Army Colonel Charles C Engel, Director of Deployment Health Clinical Center.

Source: NIDA: A Research Update from the National Institute on Drug Abuse.The Rand Corporation's study "Invisible Wounds of War" revealed a disturbing truth about the health of our military as recently as 2008: Over 300,000 returning veterans from Iraq and Afghanistan suffer from PTSD or major depression. According to the Rand report, these "invisible wounds" take a high toll—impacting veterans' quality of life, hindering their performance at work, straining their families, and placing them at greater risk for violent and self-destructive behaviors. The economic cost of these disorders is equally great—reaching as high as $6 billion over 2 years. Yet, despite the heavy toll of PTSD and depression, only half of affected veterans seek care, and only a third of those who do, receive adequate treatment. Thus, over 80% of affected veterans remain without needed help.

Since October 31, 2007, over 1.6 million troops have been deployed in Iraq and Afghanistan. According to the Rand Corporation's study, 225,000 of the returning troops suffer from PTSD, 226,000 are diagnosed with major depression, and 303,000 develop either illness.

The Transcendental Meditation technique is an effortless technique practiced 10-20 minutes twice a day sitting comfortably with the eyes closed.

TM is not a religion or philosophy and involves no new beliefs or change in lifestyle.Over 350 peer-reviewed research studies on the TM technique confirm a range of benefits for mind, body and behavior.

Several studies have compared the effects of different meditation practices and found that Transcendental Meditation provides deeper relaxation and is more effective at reducing anxiety, depression and hypertension than other forms of meditation and relaxation. In addition, no other meditation practice shows the widespread coherence throughout all areas of the brain that is seen with Transcendental Meditation.The Transcendental Meditation technique is taught in the United States by a non-profit, educational organization.
